Frequently Asked Questions
At what supply voltage does the MCP130T-300I/TT assert its RESET output, and what does that mean for 3.3 V rail monitoring?
The MCP130T-300I/TT asserts its active-low RESET output when the monitored supply falls below 3.0 V. For a 3.3 V nominal rail, this provides approximately 300 mV of headroom, ensuring that the MCU is held in reset before the supply drops to levels where undefined behavior could corrupt firmware execution or non-volatile memory writes.
How does the SOT-23-3 package of MCP130T-300I/TT compare to SC-70-3 in terms of board space savings for IoT designs?
The MCP130T-300I/TT uses a SOT-23-3 package with a body footprint of approximately 3 mm x 1.75 mm. Compared to the smaller SC-70-3 (2 mm x 1.25 mm) used on some Microchip supervisor variants, the SOT-23-3 is somewhat larger but offers easier hand-soldering and better mechanical robustness for prototyping and low-volume production builds.
What is the lead time for MCP130T-300I/TT, and is there an SMD tape-and-reel version for pick-and-place assembly?
The MCP130T-300I/TT has a factory lead time of 6 weeks. The TT suffix in the part number indicates tape-and-reel packaging, which is compatible with standard automated SMT pick-and-place assembly lines. Procurement teams should plan buffer stock for high-volume builds given the 6-week replenishment cycle.
Is the MCP130T-300I/TT suitable for watchdog or power-fail interrupt functions, or is it a simple reset supervisor only?
The MCP130T-300I/TT is a simple voltage supervisor with no watchdog timer, power-fail interrupt, or programmable reset delay — the additional feature field explicitly lists MNL RST:N, WD:N, and PRG RST DLY:N. Designs requiring those functions should consider the MCP100 or MCP130 family variants with extended features or a separate watchdog IC alongside this 3-pin supervisor.
